Understanding Supabase's Open-Source Advantage

Which of the following best explains why Supabase is considered an open-source alternative to Firebase?

A Supabase offers open-source tools and services that users can self-host or use managed, unlike Firebase's closed-source platform.

B Supabase provides a fully managed backend with proprietary closed-source services.

C Supabase only supports frontend development without backend services.

D Supabase requires users to build their own database from scratch.

💡 Hint

Think about the difference between open-source and closed-source platforms.

Supabase is open-source, meaning its code is publicly available and can be self-hosted, unlike Firebase which is proprietary.

❓ Architecture

Supabase Core Components

Which set of components correctly represents the core architecture of Supabase as an open-source Firebase alternative?

A MongoDB database, Lambda functions, Authentication, CDN

B PostgreSQL database, Realtime server, Authentication, Storage

C MySQL database, REST API only, Authentication, File system storage

D Oracle database, SOAP services, Authentication, FTP storage

💡 Hint

Supabase uses a popular open-source relational database and real-time features.

Realtime Data Updates in Supabase

What happens when a client subscribes to a Supabase Realtime channel and a row in the PostgreSQL database changes?

A The client connection is reset and must reconnect to see changes.

B The client must poll the database every few seconds to get updates.

C The client receives an immediate event with the updated row data via WebSocket.

D The client receives an email notification about the change.

💡 Hint

Realtime means updates are pushed instantly without polling.

Supabase uses WebSockets to push realtime updates to subscribed clients immediately when data changes.

❓ security

Supabase Authentication Security Model

Which statement correctly describes how Supabase handles user authentication securely?

A Supabase uses JWT tokens for session management and hashes passwords securely.

B Supabase stores user passwords in plain text for quick access.

C Supabase requires users to authenticate only once without token expiration.

Choosing Between Self-Hosting and Managed Supabase

Which scenario best justifies choosing self-hosting Supabase over using the managed service?

A When you want to use a proprietary closed-source backend.

B When you want to avoid managing any servers or updates.

C When you need a simple frontend-only solution without backend.

D When you want full control over data and infrastructure for compliance reasons.

💡 Hint

Consider reasons why organizations might prefer managing their own infrastructure.

Self-hosting Supabase allows full control over data and infrastructure, which is important for compliance and customization.
